On a Scalable Path for Multimode MIMO-DSP
Fabio A. Barbosa, Stefan Rothe, Dennis Pohle +2
A novel MIMO-DSP for space-division multiplexing over multimode fibres is proposed. A principal modes approach is shown to provide two-fold benefits: over 13 times channel memory r…
Securing Data in Multimode Fibers by Exploiting Mode-Dependent Light Propagation Effects
Stefan Rothe, Karl-Ludwig Besser, David Krause +4
Multimode fibers hold great promise to advance data rates in optical communications but come with the challenge to compensate for modal crosstalk and mode-dependent losses, resulti…
Learned end-to-end high-resolution lensless fiber imaging toward intraoperative real-time cancer diagnosis
Jiachen Wu, Tijue Wang, Ortrud Uckermann +5
Endomicroscopy is indispensable for minimally invasive diagnostics in clinical practice. For optical keyhole monitoring of surgical interventions, high-resolution fiber endoscopic…
Intensity-only Mode Decomposition on Multimode Fibers using a Densely Connected Convolutional Network
Stefan Rothe, Qian Zhang, Nektarios Koukourakis +1
The use of multimode fibers offers advantages in the field of communication technology in terms of transferable information density and information security. For applications using…
Physical Layer Security in Multimode Fiber Optical Networks
Stefan Rothe, Nektarios Koukourakis, Hannes Radner +3
Inverse precoding algorithms in multimode fiber based communication networks are used to exploit mode dependent losses on the physical layer. This provides an asymmetry between leg…
Multiphysics simulation of the aspherical deformation of piezo-glass membrane lenses including hysteresis, fabrication and non-linear effects
Florian Lemke, Yasmina Frey, Binal P Bruno +5
In this paper we present and verify the non-linear simulation of an aspherical adaptive lens based on a piezo-glass sandwich membrane with combined bending and buckling actuation.…
Diffraction-limited axial scanning in thick biological tissue employing an aberration correcting adaptive lens
Katrin Philipp, Florian Lemke, Stefan Scholz +4
Diffraction-limited focusing deep into biological tissue is challenging due to spherical aberrations that lead to a broadening of the focal spot particularly in axial direction. Wh…
